How should the corners of the toenail be shaped for optimal appearance?

Shaping the corners of the toenail to a round form is generally considered optimal for both aesthetics and health. A rounded shape helps to reduce the risk of ingrown toenails, as it allows the nail to follow the natural curve of the toe without digging into the skin at the edges. This shape is also visually appealing, as it complements the natural contours of the foot, providing a softer look compared to more angular shapes.

While square and pointed shapes can be seen in some nail styles, they may pose risks such as breakage or discomfort. A square shape, for instance, can lead to the toenail's corners catching on shoes or socks, increasing the likelihood of injury. Meanwhile, a pointed shape is often associated with certain fashion styles but can increase vulnerability to trauma and is generally not recommended for toenails, where a more natural look is preferred. Flat edges can also create sharp points that may become bothersome.

Overall, the rounded shape is favored for maintaining healthy toenails while providing an aesthetically pleasing look.
